Coolant returns via two transverse and one longitudinal conveyor into the coolant tank. The coolant is pumped from the tank as required (via M-function or switch on the control panel) through the nozzles. Mechanical sieves are provided in the coolant tank for coolant filtration.
Optional:
For internal coolant supply (ICS), a high-pressure pump with a simple filter system is available. When ICS is activated, coolant is pumped from the tank through the high-pressure pump and filter system.

Electronic handwheel
Oil skimmer in the cooling system
Blow-off and rinse guns
Chip conveyor
Automatic wireless 3D probe (Renishaw) for workpiece probing
Automatic tool breakage control (Renishaw)

The machine has only been used for a single job. As that order is no longer present, the machine is surplus to requirements.
This is a very robust machine with high spindle performance – ideal for heavy-duty machining operations.
The machine can be inspected under power at its current location.

Note: The clamping devices shown in the pictures are not part of the delivery!
Price: ex works
Dismantling, transport, and commissioning can be offered on request!
